Alesis Multimix Firewire

I’m looking at replacing my 3 terratec cards with a multimix firewire mixer (probably the 16)…does the firewire version work in Linux? My current cards are PCI, and it’s hard to find a new motherboard with enough PCI slots. I specifically want the firewire, since last I read, the USB version does not do 24 bit audio, only 16…thanks for any info!
